PERAMBULATOR.

Specification of Letters Patent.

Patented July 16, 1918.

Application filed February 20, 1917. Serial No. 149,775.

7 '0 all whom it may concern:

Be it known that I, ARTHUR J. Anna rs, a citizen of the United States, residing at Bay City, in the county of Bay and State of Michigan, have invented a new and useful Improvement in Perambulators, of which the following is a specification.

This invention relates particularly to gocalts or baby-carriages, and-is particularly applicable to folding go-carts.

The primary object is to provide a seat of simple construction and improved operation.

The invention is illustrated in its preferred embodiment in the accompanying drawings in which-- Figure 1 represents a longitudinal sectional View of a go-cart or baby-carriage embodying the invention; Fig. 2, a broken sectionalview taken as indicated at line 2 of Fig. 1 and showing a detail of the seat construction; Fig. 3, a broken plan sectional view taken as indicated at line 3 of Fig. 1; and Fig. 1, a fragmentary View of a modifi' cation.

In the construction illustrated. A represents the main horizontal frame of the gocart structure. In the form shown this frame is of U-form, the web portion constituting the front member of the frame and the arms constituting the side members. Near the central portion of the frame A. is a cross-member A having downturned extremities which embrace the side members of the frame A and are secured thereto by rivets 1. The rear ends of the side members of the frame A are connected by a. cross member A which is of U-shape, having short rearwardlyturned arms 2, which are secured to the rear ends of the side members of the frame by rivets 3.

In the illustration given, the frame A is mounted on folding wheel-brackets B, which are adapted to be folded beneath the frame A in a well understood manner. The folding structure shown further comprises handle G, which is connected near its lower end with the pivots 3 and which is also connected with the frame A by folding braces 4; also, arms D whose rear ends are pivotally connected with the side members of the handle and whose front ends are connected with links E which are connected some distance from their lower ends by pivots 5, with the side members of the frame A. The lower ends of the links E carry a U-shaped member 6, which serves in the operation of automatically folding the wheelforks in a well understood manner.

Upon the main horizontal frame A is mounted a seat F and a back G, which is foldably connected with the seat. The seat is carried by a pair of metal brackets 7, which are of general U form, so that the seat is held a couple of inches above the main portions of the brackets 7 As shown in Fig. 8, the brackets 7 are preferably so disposed as to converge rearwardly. The brackets 7 are provided some distance from their front end with'perforations S, which are engaged by the hooked rear ends of links 9, whose hooked front ends engage perforations 10 with which the cross-member A.

of the main frame is provided. The rear portions of the brackets or seat-mountings 7 are connected, by spring-links or coilsprings 11, with the rear cross-member A of'the main frame. The links 9 and the springs 11 extend substantially in a longitudinal direction and are in substantially the-same plane as the main portions of the brackets 7, it being understood that the springs 11 are initially under some tension. Thus, the brackets will be held yieldingly in a position shown in Fig. l, with their main portions substantially in the plane of the cross-members A and A of the main frame. The front vertical portion 7 of the brackets 7 are equipped with forwardly eX tending portions 7 to which the front edge portion of the seat is secured, as by bolts 12. The rear vertical arms 7 of the brackets 7 are equipped with rearwardly extending portions Secured to the portions 7 of the brackets, by means of rivets 13, is a cross-bar 14 which carries the rear portion of the seat.

Connected with the rear corners of the seat are clips or fittings 15, upon which the folding back G is mounted in a well understood manner.

H represents a folding foot-rest frame, with which is connected a foot-rest or pouch H which is usually made of leather or fabric. The rear portion of the pouch is connected with the front marginal portion of the seat, as shown. 7

From the description given, it will be understood that the brackets 7 which support the scat are suspended between the horizontal Links 9 and the horizontal coils ll, such suspension being at four points c0r respondingin a general way with the four corners of the seat. It will thus be understood that the seat is free to rock in every direction and is very sensitive in its action.

When the seat is depressed, the coi'l -spriiigs' are distended somewhat. The front portion of the seat is perhaps more sensitive in its movement than the rear portion, inasmuch as the lowering of the front edge of the seat a given distance acts apparently to distort the springs 11 less thanwould occur if the rear ends of the sea-t were depressed the. same distance. However, the seat yields readily to shock in every direction, which is a very important consideration, where the carriage is used for a very yomigchild.

In the modificationshown in Fig. 4, the link-suspension device isthe same as shown in Fig. 1, except that the front rod-form links 9 are replaced by I coil-springs, or spring links 9 This construction is somewhat superior to, but slightly more expen sive than, the construction shown in Fig. 1.

The go-cartstructure illustrated has been selected simply for the purpose of illustrating the invention. The foregoing detailed description has been given for clearness of understanding only and no unnecessary limitation should be understood therefrom, but the appended claims should be construed as broadly as permissible in view of the prior art.

What I regard as new and desire to secure by Letters Patent is:

1. In a perambulator, the combination with a frame, of a seat and tension supporting means forming the sole support for said seat, including s'eat supports and substantially horizontal spring devices disposed beneath the plane of the seat and connecting said seat supports to said frame.

2. In a perambulator, the combination with a supporting frame, of a seat equipped Copies of this patent may be obtained for with depending brackets, and tension suspension means forming the sole support for said seat and comprising means connecting the front end of said brackets moi ab'ly with the frame, and substantially horizontal coilspring connections between the rear ends of the brackets and the frame. p

3. In perambulator, the combination with a substantially horizontal supporting frame, of a seat disposed above said frame, and tension suspension means forming. the sole support of said seat and comprising link supports, including coil-springs disposed substantially in the plane of the mainframe, and seat-carrying members connected therewith. 1 V

4. In a perambulator, the combination with a main horizontal frame and crossmembers carried thereby,- of a seat disposed above the plane of said cross-members and equipped at its lower side with brackets, and link and spring connections between said brackets and said cross-members and forming therewith the sole support of saidseat.

5. In a perambulatonthe combination with a main horizontal frame, of a seat disposed above the plane thereof, a pair of substantially longitudinal bracket-s carrying said seat, links connecting said brackets'with the frame near one end of the seat, and substantially horizontal coil springs connecting said brackets with the frame near the oppo site end of the seat. I

6. In a perambulator, the combination with a substantially horizontal frame, equipped with a pairof cross-members, of a seat disposed above the plane of said frame, a pair of substantially U-shaped longitudinal brackets carrying said seat, links connecting said brackets with one cross-member of the frame, and coil-springs connecting the brackets with the other cross-member of the frame.
